The Other World spaces on the board are marked with circular
icons of different colors. These colored circles are called
encounter symbols. When an investigator has an Other
World encounter, the player draws cards from the gate deck,
one at a time, until he draws a card whose color
matches one of these encounter symbols. Gate cards that
do not match a color of the encounter symbols are
placed face down on the bottom of the gate deck.

Once the player has drawn a gate card that matches an
encounter symbol’s color, he examines it to see if there is
a specific encounter for the Other World his investigator
is currently in. If a specific encounter is listed, the player
reads that entry aloud and performs any actions indicated
by the card text. If there is no specific encounter listed,
the player reads the “Other” entry aloud and performs
any actions indicated by the card text.

The card text of an Other World encounter may result in a
monster appearing, in which case the investigator must
either evade the monster (see Evading Monsters)
or fight it (see Combat). Monsters created by an Other World
encounter do not remain on the board; once the combat or evasion is complete,
if the monster is not taken as a trophy (or returned to the box if its combat
instructions specify) then it is returned to the monster cup.

Once the encounter is
resolved, the player discards the gate card face down to the
bottom of the gate deck.

Once all investigators in Other Worlds have had their Other World encounter,
this phase ends and play continues with the Mythos phase.
